Use the data from Table B of your Student Guide to answer the questions. Be sure to round your answers to the nearest tenth. What was the acceleration of the cart with Low fan speed? cm/s2 What was the acceleration of the cart with Medium fan speed? cm/s2 What was the acceleration of the cart with High fan speed? cm/s2

Explanation:

The attached figure shows data for the cart speed, distance and time.

For low fan speed,

Distance, d = 500 cm

Time, t = 7.4 s

Average velocity for low fan speed,

Acceleration for low fan speed,

For medium fan speed,

Distance, d = 500 cm

Time, t = 6.4 s

Average velocity for medium fan speed,

Acceleration for medium fan speed,

For high fan speed,

Distance, d = 500 cm

Time, t = 5.6 s

Average velocity for high fan speed,

Acceleration for high fan speed,

1. The acceleration of the cart with Low fan speed is 9.12 cm/s².

2. The acceleration of the cart with Medium fan speed is 12.2 cm/s².

3. The acceleration of the cart with High fan speed is 15.94 cm/s²
